REGISTER.

Specification of Letters Patent.

Patented June 22, 1915.

Application filed March 4, 1914. Serial No. 822,357.

To all whom it may concern:

Be it known that I, JAMEs H. BAILEY, a citizen of the United States ofAmerica, and residing at Brooklyn, in the county of Kings and State ofNew York, have invented new and useful Improvements in Registers, ofwhich the following is a specification.

My invention relates particularly to what are commonly termed heatingand ventilating registers.

Devices of this character are usually provided with a grille or screenfor preventing access of foreign matter into the flue with which theregister is connected. It is desirable that this grille whileeffectually guarding the mouth of the register shall not materiallyimpede the flow through the register. Increase in flow capacity hasheretofore been obtained by increasing the size of the openings in thegrille and this naturally results in a corresponding decrease orsacrifice in the capacity of the grille as a barrier or guard.

My invention has for one of its objects to gain increased flow capacitywithout in any way sacrificing the barrier or protective qualities ofthe register. This object I have attained by employing two grilles,disposed one over the other and with the webs forming the meshes of onegrille spaced from and disposed out of alinement with the webs formingthe meshes of the other grille. The result of this is a composite grillewhose capacity as a barrier is equivalent to the sum of the two grilleswhile the intervening air space between the grilles allows a greatervolume of air to pass through the two grilles than if the two grilleswere combined in one plane.

Another object of the invention is to make the register as ornamentaland attractive in appearance as possible. The use of the two grilleslends itself admirably to this purpose since by varying the design,shape or color of the respective grilles a great variety of effects maybe produced and the parts of the inside grille appearing through theopenings in the outside grille give a sense of perspective to thecomposite design.

The accompanying drawings illustrate lIl concrete form a practicalembodiment of my invention, but it will be understood that variouschanges and modifications may be made without departing from the truespirit and scope of the invention.

Figure 1, is a front View of a so-called base-board register embodyingand typifying the invention. Fig. 2, is a perspective disassembled viewof the same. Fig. 3, is a vert cal sectional view of the register as-inuse 1n connection with the flue box of a wall flue. Fig. 4, is afragmentary sectional view of a slight modification in the form of theinner grille.

The outer frame or border member of the register is designated 7 in thedrawings and as in this particular instance it is to fit the base boardof the room it is shown provided with a rearwardly extending top wall 8and rearwardly extending end walls 9, which as indicated in Fig. 3 fitin the corner formed by the side wall and floor of the room.

The outer grille is carried by the border frame and in the caseillustrated it is formed integral therewith. This grille, as best shownin Fig. 2 consists of a series of angularly disposed bars or webs llspaced to leave eXit openings 12 therebetween.

The inner grille is shown carried by an inside frame 15 and it alsoconsists of a series of webs or bars 16 spaced to provide openings 17therebetween. This second or inner grille is disposed inside of andseparated from the outside grille by an intervening clear space 18 andthe webs of the inside grille are disposed out of alinement with thewebs of the outer grille so as to cross the spaces or openings in theouter grille. In the construction illustrated the webs of the outergrille form squares disposed in horizontal rows while the webs of theinner grille form smaller squares arranged in inclined rows, the effectbeing when the register is assembled, a composite design (Fig. 1)consisting of heavy squares in the foreground crossed by diagonalsappearing in the background.

The inner frame is supported preferably by being detachably secured tothe outer frame. In the illustration this is accomplished by employingscrews 21, passed through openings 22 in the border frame into tappedopenings 23 in the inner frame. I prefer also to use the inner grilleframe 'as a mounting for the fan or valve. I have therefore shown thefan 25 as pivoted at 26 in the rearwardly extending flange 27 of thisframe and operated by a hand lever 28 pivoted' at 29 and provided with asegmental slot 30 engaging over a stud 31 on the end of the fan.

V The grilles may be made integral or separate from their supportingframes. Thus in Figs. 2 and 3 the inner grille is shown as made up ofinterlaced bars having their ends engaged in seats 33 in the rearwardly'extending flange 27 of the frame while in Fig. 4 I have shown the webs35 of the inner grille as formed integral with the frame. The innerframe in this case also is shown'provided with the rearwardly extendingflange 36 to house the fan when in its lowered or closed position. Thebearing for the supporting screws 21 is provided in this instance bycutting and bending up a lug 37 or lugs out of the rearward extendingflange 36.

In Fig. 3, the register is shown applied to the outlet 40 of a flue box41. This view illustrates clearly how the two grilles form acompositegrillework whose practical eflect as a barrier is equal to thesum of the two grilles but which on the other hand are capable ofpassing a volume of air or other fluid greater than if the two grilleswere combined in one plane.

As the inner grille is to a large extent protected by the outer grille,it may be made considerably lighter and of less expensive material thanthe outer grille. This means a reduction in weight and a consequentsaving in the cost of manufacture and expense of shipping and handling.By keeping a number of designs of the inner and outer grilles in stock agreat'variety of composite designs may be produced on demand and by 7making up the grilles in different colors in- Q'opies of this patent maybe obtained, for

numerable ornamental effects may be obtained.

What I claim is 1. In a register and ventilator, an outer grilleconsisting of webs relatively narrow and spaced widely apart to provideopenings between them of greater area than said webs to therebyconstitute a grille whose major portion is made up oi: air passages, andan inner grille disposed behind the outer grille and consisting of websdisposed in line with the air passages in the outer grille and narrowerthan said passages to thereby interrupt the expanse of the passages inthe outer grille without shutting off direct flow through said passagesand to thereby constitute a compound grille whose design is a compositeof the webs in the outer grille and the webs in the inner grille visiblethrough the passages in the outer grille.

2. A register comprising an outer member having a plurality ofintersecting narrow bars forming a grille and rearwardly projecting'border flanges in combination with an inner member having border flangesand narrow intersecting bars forming a grille and means for detachablysecuring said inner and outer members together with the grilles inspacedapart relation, the narrow bars of the inner grille being in linewith the spaces between the narrow bars of the outer grille.
